If the goal is to be annoying, sure make sure folks can jump through hoops. I just don't think in 2025 a company legitimately intending to satisfy the GPL requirements needs anything to do with physical mail, since they'll provide it online.
I stopped putting in requests for source code offers because I've had a 0% success rate.
Companies don't legitimately intend to satisfy the GPL requirements.
If you put in a source code request and get no reply you should try to contact the copyright holder or someone like the Software Freedom Conservancy or the EFF, because they are breaking the law. There was a case recently in Germany where a court forced a maker of home routers to give up not just their source code, but also the scripts to install modified software - as required by the license. (As I understand it there is no precedent in a civil law system, but it does mean at least one judge believes Tivoization of GPLv2 software is illegal)
I am keeping an eye on SFC's lawsuit against Vizio[0].

Please let the Software Freedom Conservancy know about any companies that are still in violation of the GPL by not satisfying requests for source code.
